abstract="BACKGROUND: Button battery ingestions have emerged as an increasing medical issue in recent years, especially for children. The frequent use of these energy sources in  small appliances and toys is responsible for their ubiquitous occurrence in  households. In addition to other possible foreign bodies, button batteries are  particularly dangerous as they can cause severe complications in the aerodigestive  tract. <br><br>OBJECTIVE: The study aimed for a detailed analysis of specific radiographic  identifiers of button batteries and similarly configured potential esophageal  foreign bodies in high-resolution X-ray scans. <br><br>METHODS: A selection of potentially  hazardous button batteries - in cases of ingestion (CR2032) or aspiration (LR44,  LR1130) - was made. Other clinically relevant radio-opaque objects of similar size  and shape have been selected accordingly. High-resolution X-ray scans (33.3 lp/mm)  were made using an in vitro model in porcine esophageal preparations. A systematic,  comparative analysis was carried out with the digital radiographic images. <br><br>FINDINGS:  In the study described, the selected foreign bodies were scanned at distinct angles  in high image quality. Using button batteries, radiographically details of their  internal structures were shown that have not yet been described. The known markers,  as well as new detailed characteristics, were found in the experimental setting. The  differentiation from other typical esophageal foreign bodies was possible by  analyzing four relevant identification features: the edge properties, internal  structures, the size, and differences in 0°/90° scans. <br><br>CONCLUSIONS: The study  results reveal that specific features of potential esophageal foreign bodies can be  identified by improved radiographic resolution, contrast, and dynamics. Thus, the  diagnostic reliability in distinguishing 'high-risk foreign bodies' from less  dangerous ones could be increased. In the future, button batteries could be detected  more reliably with intelligent digital image analysis and enhanced radiographic  technology. This may further support clinical triage algorithms and help reduce  medical complications in cases of foreign body ingestions.<p /> <p>Language: en</p>",
